Rangemaster and impeadence

[samrsmiley]

I finished a range master clone, and tried it on a gig.  I used a volume/wah, and Keeley mod TS7 before, and old Small stone and wampler analog delay after to an AC30.  Now the thing sounded WAY tinier than trying it on a VAmp (yea the POD knock off) when I tried it to see if it worked-like unusably tinier. 
I just found this: http://www.guitar-pedals-effects.com/Rangemaster.html  which seems like using effects before the rangemaster somehow increases the treble because of impedance.  Can someone explain this?  I honestly don't have a good grasp on impedance and how it affects effects (dig that affect effects!), and only kind of understand how it works when using a speaker with an amp head. 
Is there a way to still use the pedal with other pedals, or does it have to be the only one in the chain?  Can it come first without those other pedals affecting the impedance (I'm guessing the Ibanez TS7 did it)?  Thanks for any help!

The Rangemaster is, after all, a  treble booster.
First in the chain would be best but it depends on what you want it to do...

I might be worth using an emitter follower before the TB, this should stabilize the input impedance of the TB so that the output tone is more predictable. A opamp buffer would achieve the same thing but adds more circuitry.

Part of the rangemaster sound is the way it's low Zin interacts with passive pickups. It's low input impedance loads the guitar pickup in a way that smooths the highs and helps the guitar volume control clean it up. So it really depends on being driven by a high impedance source to sound "good". Otherwise it will sound too bright and thin. It's effectiveness also depends on how it interacts with the amp. I don't like buffered pedals before or after the rangemaster, and usually keep it in an isolated loop by itself. How well a true-bypass pedal works with it (when said pedal is switched on) depends on what it is, I guess. I think the best way to use delays and other "post distortion" fx with a rangemaster would probably be in an amp fx loop, I suspect.

A good treble booster doesn't boost treble, it boosts upper mids (despite the name). I.e you boost the signal, cutting a lot of bass and some treble. If you have nothing to limit the treble it just gets way too bright. As Doug said, the guitar directly into the Rangemaster will loose lots of treble due to the low input impedance. The TS acts as a buffer which means there will be no treble loss in the Rangemaster and thus way too bright tone.

The easiest solution is simply to roll off the tone knob on the guitar a bit when using the Rangemaster.

Or, one solution that ive implemented, you could put a 10k R between the guitar signal and the RMs input
